@mcc @glyph I think that’s a little unfair to red hat (it’s just *more inconveniently* available now) but as a general matter, yeah. In particular:
1️⃣ copyleft has always been mostly in practice less legal contract, more social contract (though there are important exceptions); and
2️⃣ because it is ~ impossible to revise, over time copylefts almost always become *less* contractual because lawyers for users are constantly shrinking them, while lawyers for creators are rarely expanding them.
